The 19-year-old placed 30th, while her coach and mentor, Katie Compton, scored a podium spot for the USA team. Compton finished second to Dutch rider Marianne Vos.

Antonneau told CXMagazine: "I rode myself into the ground. I did the best that I could so I am happy with how it went. I did junior worlds on the road last summer but this is pretty big! I still think I am a little too young to choose between road and cylcocross [to specialize in] but I really like cyclocross a lot so I want to keep doing it.”

Compton, riding for Madison-based Planet Bike, had great expectations going into the World Championship, after winning fives times on the World Cup circuit. Vos, however, proved unbeatable. She surged away from Compton and Katerina Nash over the final lap to secure her third straight world title.

Compton shared this post-race assessment: “I wanted to keep the pace up and reduce the pack. It was a tactic to keep it fast, it’s better to go over the ruts fast, so I wanted to keep the pace up. I did all I could do. Vos was faster at the end. Worlds was the one I wanted to win, this was a tough day for me.”

In the men's championship, Zdenek Stybar won his second straight world title, ahead of Sven Nys. Jonathan Page, another Planet Bike rider, led the USA group with a 12th place finish.
